Alarm / Immobiliser

[panda]

I was looking at the Toyota / Lexus V8 forum the other day and saw a post from sombody asking how to hotwire his LS400 to bypass the immobiliser and start it. Somebody else obligingly posted the relevant part of the wiring diagrams of the LS400 to show him how to do this together with added hotwire clearly marked! Presumably the same could be done to any Lexus? My question is - is there any point at all in getting a seperate immobiliser alarm? Presumably that could be bypassed by hotwiring too? So if they can get into your car there is nothing that can stop em stealing it?

How old was the LS400? They used to has separate alarms/immobilisers which like any third party alarm can be bypassed.

All new Lexus vehicles (from 1998 onwards) have immobilisers built into the engine ECU, you cannot bypass them and it is also difficult to defeat them.

The LS430 is continually voted the most secure vehicle in the UK.

Phew!

thanks for that Colin

To reiterate the point

You cannot 'hotwire' newer vehicles (generally post 1997) - it is virtually impossible. Older vehicles, generally Japanese vehicles, were brought into this country at port without any form of immobiliser sytem and were fitted at the port with aftermarket systems, which were easy to bypass.

Sophisticated computer software together with considerable time and effort is required to bypass any system at the roadside and it is not viable for a thief to invest such resources.

The only way it can really be done at the roadside is by having a seperate ECU, wiring loom, keys and ignition for the vehicle and replacing the parts - again not practical.

It is far easier to break into your home and steal your keys, hence the increase in housebreakings (burglary) in your local area.

Rest easy.

Phew! and phew! again! Good point about the keys in the house though- better find somewhere obscure to find them.
